HELOC on house being re-modeled

I want to get a HELOC to re-model my primary home. My HELOC was approved but the day I went to sign the loan acceptance learnt that a much lower introductory rate was available. So decided not to accept the loan but reapply. Meanwhile re-modeling started and now the bank refuses to approve new loan application since home is in the process of getting re-modeled.

 

Any advice?
